I agree there were a lot of things about Europe 99 that I miss. One interesting comparison to make beyond the map divisions, are the relative IPC values of specific territories or regions, and how those changed from the Europe 99 board, to the current Europe 1940.
This stuff makes me feel that the value of 1 ipc in A&A does not really correspond to anything concrete at the low end, at least in terms of the abstract “industry” its meant to represent.
So for example the region corresponding to “Germany” on the Europe 99 board is worth 6 ipcs, this same region is worth 10 ipcs in 1940. Romania was worth 1 ipc in Europe 99, but 3 ipcs in Europe 1940 etc.
But then you have other territories like Poland, E. Poland and Baltic states that remain at the same value, despite the supposed increase in economic scale. Basically the give and take at 1 ipc seems flexible, sometimes increased sometimes lowered.
So in addition to the actual territory divisions, I think you could make a case for more tweaking of the ipc values.
Greater Southern Germany always struck me as a rather weird name. Why give Tyrol/Innsbruck to West Germany anyway? Seems like it would have been easier to just have Austria as a complete territory running all the way to Switz, as pointed out above, for the gameplay vs the med. The 110 split is also an interesting idea
